EXTRACTING 01L FROM'COTTON-SEED.

SPECIFICATION forming'parb'of Letters Patent No. 281,566, dated July 17,1883.

l 7 Application filed April 25,1883. (No specimens.) I i T 0 all whom itmay concern:

Be it known that we, SAMUEL SoHEIBLER and ADoLE SoHEIBLER, both ofMemphis, in the county of Shelby and State of Tennessee, have invented anew and useful Improvement in Extracting Oil from Cotton-Seed, of whichthe following is a description.

Our invention consists of preparing cottonseed for the more effectualand easier separation of the oil by means of a press than isaccomplished by the common process.

Instead of the common method of roasting the crushed seed with dry heattill it becomes almost like parched coffee before subjecting it to thepress, we propose to take the crushed seed and add a sufficient quantityof water, and then stew and boil it until all the pores of the seed arethoroughly open and the fibers of the seed are soft and pliable, then topress the seed in the same manner as it is now done, whereby we gainpractically from fifteen to twenty-five per cent. more oil, at the sametime using less power to'work the press, which is the result of thegreater effect that the pressure takes 011 the softened seed and themore 2 5 free escape thereby afforded to the oil.

WVe are aware that it is not new to inject water or steam upon the seedbefore crushing it; but this-renders the crushing more difficult andless perfect, as well as thus prevents a full 3O expression of the oil.We are also aware that the meal has been moistened previous toexpressing the oil; but we are not aware that any one has boiled themeal in water so as to dis-' integrate the oil and fiber and cause acomplete 35 separation under pressure; hence What we claim is A processof obtaining oil from cotton or other seeds, which consists in firstgrinding or water until the the fiber is softened and the 4 poresopened, and then expressing theoil, as

described.
